Definitions

• the invention relates to the field of manufacturing objects provided with profiled plastic elements, such as glazing provided with ornamental profiles or sealing. It relates more particularly to a method for shaping a portion of an extruded profiled bead on an object, and to articles resulting therefrom, as well as a device specially studied for implementing this method. It is generally known to deposit profiled polymer cords, for example along the edge of a window pane, by continuous extrusion and to use them directly as a sealing profile, in particular for glazing units mounted by gluing in a frame.
• Appropriate sections of profiles facilitate, on the one hand, the centering of the glazing when it is mounted in a frame or chassis, for example in a bodywork bay, and on the other hand, guarantee the position of the glazing during the time of hardening of the glue usually used.
• extrusion has the advantage of greater flexibility since it is not necessary to keep a mold specific to each form of window, but it suffices to guide a die d extrusion with a calibrated section along the edge of the glass, controlled by a programmable robot, with a defined material flow, generally continuous.
• Certain existing solutions thus adapt the section of the cord by cutting a determined section of the cord in a corner or connection zone and by filling the voids thus created by the injection of an additional material which joins the profiled cord (EP- B 0 524 060), or add additional material for filling the angles by injection on the corder, a continuous section of regular section, in a work phase after the extrusion (cf. DE-C-195 37 693.
• the glazings are, up to now, removed from the extrusion station before the retouching of the profiled bead and are positioned, again, in a separate retouching station.
• the extrusion station therefore has the best possible occupancy rate, because before injecting additional material or partial cutting and filling the vacuum created, a waiting time must be observed until the extruded material is sufficiently stabilized.
• patent DE 44 45 258 C2 it is also already known to touch up the connection zone between the start and the end of a profiled bead of extruded polymer surrounding the edge of a window, by means of a multi-part pressing mold.
• Another known pcst-forming tool (DE-U-90 11 573 ⁇ for profiled extruded polyurethane cords is also designed in such a way that the panes must be positioned relative to the device and cannot therefore be touched up directly. in the extrusion station.
• the object of the invention is thus to present a method which achieves a marked improvement in retouching, in particular by reducing the waiting time for the post-forming of critical zones of a profiled bead, in particular corner zones. and / or connection areas.
• a corresponding device advantageously as compact as possible, especially suitable for the implementation of this process, can also be proposed.
• the subject of the invention is therefore a method for shaping a portion of a profiled bead extruded onto an object, in particular a window pane, in which a mass of initially shapeless material is produced in the portion concerned and is brought to desired final shape by contact with a shaped surface of a movable tool, any excess material being automatically forced out of the tool to be eliminated, characterized in that the mass of material is produced by the superposition of two segments of extruded profile with the following steps: the extrusion die is guided along a first segment of the planned course of the profiled bead including the portion to be shaped,
• the method according to the invention is characterized in that the supply of this material, necessary for the final shaping, is carried out directly at the time of extrusion, so that after the die has left the zone concerned, it can proceed to retouching at the same time as the extrusion ends.
• This process is particularly useful for locally making particular shapes in areas

• the first and / or the second segment extend beyond the outline of the object, so that the shaped portion overflows beyond the edge and the edge.
• material accumulation is formed by moving the die after extrusion of the first segment, in t i passed above the zone of the first segrrent including the portion to be shaped.
• the material thus forms in the area concerned a kind of ribbon folded back on itself, in which the superimposed layers (or folds) adhere perfectly to each other.

• an article, in particular glazing comprising an object, in particular a window, provided with a profile bead extruded onto the object, having at least one angular portion,
• RECTIFIED SHEET (RULE 91) ISA / EP characterized in that at least one angular portion is constituted by the superposition of at least two partial cords which adhere to one another according to a possibly skin-like interface, which is shaped by contact with a shaped surface.
• the material deposited on the first partial bead may undergo a partial modification before the material of the second bead partial is not superimposed on it.
• the plastic in the shaped area is generally relatively heterogeneous, although giving the bead a satisfactory cohesion by adhesion of the respective layers to each other.
• the extruded material is advantageously of the thermoplastic type, preferably a thermoplastic elastomer (TPE) or a thermoplastic olefin (TPO). Preference is given to materials not having an excessive tack (tac iness), in order to facilitate the shaping operations, in particular the separation of the shaped surface.

By guiding the die in the new direction of progression along the next side, according to arrow Fb, we form a second segment of cord 2b. It is not necessary to interrupt the extrusion process during the transfer of the die. The extrudate is therefore applied in duplicate in a limited area, ic by crossing the superimposed portions, in a comparable manner at the beginning and at the end of the profiled cor ⁇ on, with the difference that the deposition of the upper portion immediately follows the deposition of the lower portion.

• the corner area can also be shaped with a rib or the like running through the upper face of the profiled bead.
• the cited outer contour of the flat seal 23 thus serves to form and limit the edge of the profiled bead 2, facing towards the middle of the window, in the corner area. It thus also forms an angle which corresponds to the opening angle of the lower part of the mold and aligns exactly with it. In the corner area, this break is however sufficiently rounded for a small delivery space to form between the material accumulation area 4 and the front edge of the joint. The material pushed back towards the middle of the glass during post-forming can fill it. On the other side beyond the window 1, the excess material which is driven back into the cited cavity is cut between the cutting edge 19 and the underside of the punch 20 and falls out of the tool at the latest when the latter returns to its rest position. Prototypes have shown that, in general, no material residue remains stuck on the cutting edge and that stuck remains can easily be removed. However, the jack 21 of the punch 20 must not exert too high forces so that the rigid connection 22 does not have to be of a particularly robust design.
